I have read and heard, from end users, that the A-5 buffer shoots smother. My question is why?
They often attribute the softer/smoother recoil impulse to the longer receiver extension. I know the A-5 receiver extension is approximately 3/4 inch longer than a carbine length extension, but the distance traveled by the A-5, carbine and rifle buffer is the same or very close to. It has to be. If the distance the buffer travels was increased the gas carrier key would slam into the lower receiver just above the receiver extension.
So, if the distance traveled by the buffer is the same, what is it about the A-5 buffer system that makes it shoots smoother? Is it the weight of the buffer? Carbine buffers can be purchased in the same weight, so wouldn't they have the same recoil impulse? Is the reason the A-5 buffer shoots smoother the reciprocal weight? This is the one variable that seems the most plausible to me and the one that I may not be able to duplicate in a carbine length system. (I would have to do more research into it before I could say for certain)
The rifle length spring is not the reason as the buffers in all three of the extension lengths travel approximately the same distance. The spring rate of the rifle has been duplicated in a carbine length system.
I must admit I have not shot an A-5 equipped rifle. This should not be an issue as I am not doubting they work. I am inquiring as to why they work.
Thanks
And by the way, I did perform a search.
